Opencart module/calendar for reservations

The idea would be to be able to include, whenever necessary, a simple calendar in the products for customers to make reservations such as a hotel or guesthouse. When customers select the desired dates to checkin and checkout, add to cart and buy / pay for them, those dates are automatically filled/blocked so that nobody else can reserve them. Summarizing is an integration of a simple calendar with the possibility to make reservations of dates of entry and exit and after this purchase they are blocked because they are already occupied.
